While photoluminescent exit signs have been available for quite a long time, a new generation of photoluminescent product designs have ushered advanced photoluminescent emergency exit signs into mainstream use. With the modern luminosity and increased luminance duration of photoluminescent exit signs, it makes sense that many building codes are now incorporating the use of new generation photoluminescent exit signs into the mainstream, through the implementation of laws and regulations. What we mean by photoluminescent materials involves a special inorganic pigment that is incorporated into the lettering of the exit sign. The luminescent pigments used in the sign absorb and store energy from normal, ambient light. In the case of sudden darkness, such as a power outage or the rapid spreading of smoke throughout a room, hallway, or corridor, the glow in the dark exit sign releases the stored energy in the form of a luminous glow and becomes immediately visible, so people can quickly evacuate to safety.
According to recent statistics from the U.S. Department of Energy, there are over 100 million electric exit signs operating across the country twenty-four hours a day, seven days a week. The companies, schools, government facilities, hotels, and other public buildings that use these electric signs pay a combined cost of over one billion dollars a year in energy and maintenance costs. When it comes to saving on energy costs and reducing company overhead, photoluminescent exit signs are clearly the perfect solution. By switching to photoluminescent exit signs, it is estimated that companies in the United States can save thousands of kilowatts of electricity each year. That shocking figure translates to an annual energy cost savings that exceeds the hundreds of millions of dollars mark.
As we see national safety trends moving towards the mandated addition of low-level exit signage and emergency egress systems, such as photoluminescent materials, United States businesses, including both public and private institutions, will try to save money on product installation and maintenance costs. Photoluminescent exit signs and egress pathway components can save you money in many ways:
· Compared to electric exit signs, photoluminescent exit signs are simple to install and require no additional electricity to operate, meaning your company will not incur the additional labor and electrical costs associated with the installation of electric exit signs.
· Whereas electric exit signs also require electricity to operate the individual components, photoluminescent exit signs are fueled by the absorption and storage of ambient fluorescent light and require no additional electricity to operate.
· Maintenance costs are lower with photoluminescent exit signs. Most electric exit signs are illuminated with light bulbs, and light bulbs frequently and easily break and burn out over time. There are no bulbs to replace with photoluminescent exit signs, and once installed photoluminescent exit signs are easily maintained for over twenty-five years. This increased reliability also ensures against potential life safety hazards that could result form a lack of maintenance for electric exit signs.
